Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Verschwei ßen von Metallteilen und zum Verschweißen von Kunststoffteilen wie zumindest bereichsweises Umschließen der verschweißten Metallteile mit den Kunststoffteilen mit einer eine Sonotrode und zumindest einer dieser zugeordneten ersten Gegenelektrode auf weisenden Ultraschallschweißvorrichtung, wobei die zu ver schweißenden Metallteile zwischen der Gegenelektrode und einem ersten Sonotrodenflächenabschnitt anordbar sind, der parallel zur Sonotrodenschwingungsrichtung verläuft. Ferner bezieht sich die Erfindung auf ein Verfahren zum Verschweißen von Metallteilen und zum Verschweißen von Kunststoffteilen und auf die Verwendung der Vorrichtung zum Verschreiben von elektrisch leitenden Elementen.The invention relates to a device for welding metal parts and for welding plastic parts such as at least partially enclosing the welded Metal parts with the plastic parts with a sonotrode and at least one associated with this first counter electrode pointing ultrasonic welding device, the ver welding metal parts between the counter electrode and one first sonotrode surface section can be arranged, which is parallel to Direction of sonotrode vibration. Furthermore, the Invention on a method for welding metal parts and for welding plastic parts and on the use of the Device for prescribing electrically conductive elements.
Um z.B. elektrische Leiter zu einem Knotenpunkt zu verbinden und diese Stelle mit einer elektrisch isolierenden Umhüllung zu versehen, sind Vorrichtungen bekannt, in denen zwei Sonotroden mit dieser zugeordneten Gegenelektroden integriert sind. Die durch die Sonotroden und diesen zugeordneten Gegenelektroden gebildeten Schweißstationen sind im Abstand zueinander in der Vorrichtung angeordnet, um so bedienungsfreundlich zunächst Metallteile zu verschweißen und sodann zu umhüllen. Eine entsprechende zwei Schweißstationen umfassende Vorrichtung ist jedoch recht kostenaufwendig, da erwähntermaßen für die unter schiedlichen Schweißvorgänge getrennte Sonotroden und Gegen elektroden und Steuereinheiten erforderlich sind. Zwei Schweiß stationen sind jedoch erforderlich, da die zu verschweißenden Flächen der Metall- bzw. Kunststoffteil in unterschiedlichen Richtungen zu der Schwingungsrichtung einer Sonotrode ausge richtet werden müssen.To e.g. to connect electrical conductors to a node and this point with an electrically insulating covering provided, devices are known in which two sonotrodes are integrated with the associated counter electrodes. The through the sonotrodes and associated counter electrodes Welding stations formed are at a distance from each other in the Device arranged so as to be easy to use initially Weld metal parts and then encase them. A corresponding device comprising two welding stations however quite expensive, as mentioned for the below different welding processes separate sonotrodes and counter electrodes and control units are required. Two sweats Stations are required, however, because the ones to be welded Areas of metal or plastic part in different Directions to the direction of vibration of a sonotrode out must be judged.
So muß die Schweißfläche bei Metallteilen parallel zur Sonotro denschwingungsachse verlaufen. Zusätzlich muß eine Krafteinwir kung auf die zu verschweißenden Teile appliziert werden, was mittels der Gegenelektrode erreicht wird.The welding surface for metal parts must be parallel to the Sonotro vibration axis. In addition, a force must be applied What can be applied to the parts to be welded is achieved by means of the counter electrode.
Beim Kunststoffschweißen läuft dagegen die Sonotroden schwingungsachse senkrecht zu den zu verschweißenden Flächen, so daß infolgedessen bei den bekannten Vorrichtungen für jede Schweißstation eine gesonderte Sonotrode Verwendung findet, insbesondere dann, wenn ein im Querschnitt einstellbarer Ver dichtungsraum zur Verfügung gestellt werden soll. Dies ist beim Verschweißen von elektrischen Leitern zu Knotenpunkten und deren anschließender Umhüllung mit Kunststoffmaterial der Fall.In contrast, the sonotrodes run in plastic welding axis of vibration perpendicular to the surfaces to be welded, so that consequently in the known devices for each Welding station uses a separate sonotrode, especially when a cross section adjustable Ver sealing space should be made available. This is with Welding of electrical conductors to nodes and their subsequent covering with plastic material is the case.
Aus der US-PS 42 08 001 ist zwar bereits der Vorschlag bekannt, daß mit einer Ultraschallschweißmaschine wahlweise Metallplatten untereinander oder ggf. auch Kunststoff verschweißt werden kann. Um die Ultraschallenergie in geeigneter Art zu applizieren, muß zum Verschweißen von Metall eine Hilfskonstruktion benutzt werden, durch die eine Umlenkung der Schwingungsrichtung um 90° erfolgt. Hierzu geht von der Sonotrode ein Kupplungselement aus, welches mit einem Werkzeug verbunden ist, das mit einem freien Ende auf zu verschweißende Metallplatten anlegbar und mit seinem anderen Ende an einem Punkt einer Abstützung festgelegt ist. Um diesen Punkt kann sodann das Werkzeug geschwenkt werden, um so mit dem gegenüberliegenden Ende auf den zu verschweißenden Metallteilen hin- und herbewegt zu werden. From US-PS 42 08 001 the proposal is already known that with an ultrasonic welding machine either metal plates are welded to one another or, if necessary, also plastic can. In order to apply the ultrasonic energy in a suitable way, an auxiliary structure must be used to weld metal are deflected by the direction of vibration 90 °. For this purpose, a coupling element goes from the sonotrode which is connected to a tool which is connected to a free end can be placed on metal plates to be welded and with its other end set at a point of support is. The tool can then be pivoted about this point be so with the opposite end towards the welded metal parts to be moved back and forth.
Die Vorrichtung nach der US-PS 42 08 001 sieht nicht die Mög lichkeit vor, wahlweise Kunststoff oder Metall zu verschweißen, ohne daß konstruktive Veränderungen am Aufbau der Maschine selbst vorgenommen werden müssen.The device according to US-PS 42 08 001 does not see the poss possibility of welding plastic or metal, without constructive changes to the construction of the machine must be made by yourself.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung und ein Verfahren der eingangs genannten Art so auszubilden, daß mit konstruktiv einfachen Mitteln wahlweise Metall oder Kunststoff mittels Ultraschall verschweißt werden kann, ohne daß von der Sonotrode Verbindungselemente zum Umlenken der Schwingungs richtung ausgehen müssen und ohne daß die Sonotrode umgebaut oder mit Teilen ergänzt werden muß, wenn nach einem Metallver schweißen Kunststoff geschweißt werden soll oder umgekehrt.The object of the present invention is a device and a method of the type mentioned in such a way that with structurally simple means either metal or plastic can be welded by ultrasound without the Sonotrode connecting elements for deflecting the vibration direction must go out and without the sonotrode rebuilt or must be supplemented with parts if after a Metallver welding plastic to be welded or vice versa.
Die Aufgabe wird erfindungsgemäß im wesentlichen vorrichtungs gemäß dadurch gelöst, daß einem senkrecht zur Sonotroden schwingungsrichtung verlaufender zweiter Abschnitt derselben Sonotrode eine weitere Gegenelektrode oder ein Abschnitt der ersten Gegenelektrode zur Bildung einer Aufnahme zum Ver schweißen des Kunststoffes zugeordnet ist. Dabei ist die Aufnah me vorzugsweise ein Verdichtungsraum, der in seinem Querschnitt einstellbar ist.The object of the invention is essentially device solved according to that perpendicular to the sonotrodes second section of the same Sonotrode another counter electrode or a section of the first counter electrode to form a receptacle for ver welding of the plastic is assigned. Here is the recording me preferably a compression space in its cross section is adjustable.
Erfindungsgemäß wird folglich ein und dieselbe Sonotrode be nutzt, um mit dieser unmittelbar wahlweise Metall- oder Kunst stoffteile zu verschweißen. Hierzu sind Umbauten an der Sono trode nicht erforderlich. Auch müssen von der Sonotrode keine Hilfseinrichtungen ausgehen, um die Schwingungsrichtung umzu lenken. Vielmehr werden nur senkrecht zueinander verlaufende Sonotrodenflächenabschnitte genutzt, die mit den zu ver schweißenden Teilen zusammenwirken, wobei diese Sonotrodenflächen abschnitte entweder senkrecht oder parallel zur Sonotroden schwingungsachse verlaufen.According to the invention, one and the same sonotrode is consequently be uses to choose directly with this metal or art to weld fabric parts. For this there are modifications to the Sono tode not required. There is also no need for the sonotrode Auxiliary devices go out to change the direction of vibration to steer. Rather, they are only perpendicular to each other Sonotrode surface sections used with the ver welding parts interact, these sonotrode surfaces sections either perpendicular or parallel to the sonotrodes oscillation axis run.
Bei einer erfindungsgemäßen Vorrichtung können folglich problem los mit einer einzigen Sonotrode elektrische Leiter zu Knoten punkten verbunden und sodann elektrisch isolierend umhüllt werden, indem die Elemente in Aufnahmen bzw. Verdichtungsräume eingebracht werden, die abschnittsweise von einer einzigen Sonotrode begrenzt werden.In a device according to the invention, problems can consequently arise go to nodes with a single sonotrode dots connected and then encased in an electrically insulating manner the elements in recordings or Compression spaces are brought in, the sections of with a single sonotrode.
Vorzugsweise ist ein peripherer Sonotrodenkopfabschnitt eine Begrenzung beim Verschweißen von Metallteilen, wohingegen ein Stirnflächenabschnitt des Sonotrodenkopfes die Begrenzung einer Aufnahme- bzw. eines Verdichtungsraumes für das Kunststoff schweißen bildet. Hierdurch bedingt sind die Aufnahmen für die unterschiedlichen Schweißprozesse dicht nebeneinander gelagert, so daß eine einfache Handhabung erfolgt.Preferably, a peripheral sonotrode head section is one Limitation when welding metal parts, whereas a End face section of the sonotrode head limiting a Recording or a compression space for the plastic welding forms. This means that the recordings for the different welding processes stored close together, so that it is easy to use.
Ein Verfahren zum Schweißen von Metall- und Kunststoffteilen mit einer eine Sonotrode und zumindest eine Gegenelektrode aufwei senden Ultraschallschweißvorrichtung zeichnet sich dadurch aus, daß die Sonotrode zum Verschweißen von sowohl Kunststoff als auch Metall unmittelbar benutzt wird, in dem die Kunststoff- bzw. Metallteile mit zwei Sonotrodenabschnitten und diesen zugeord neten Abschnitten einer oder mehrerer Gegenelektroden in Wech selwirkung gebracht werden, wobei von den Sonotrodenab schnitten einer parallel und der andere senkrecht zur Sonotroden schwingungsrichtung ausgerichtet wird.A process for welding metal and plastic parts with one has a sonotrode and at least one counter electrode send ultrasonic welding device is characterized by that the sonotrode for welding both plastic and metal is also used directly in which the plastic or Metal parts with two sonotrode sections and assigned to them sections of one or more counter electrodes in alternation be brought together, from the sonotrodes one cut parallel and the other perpendicular to the sonotrodes direction of vibration is aligned.
Insbesondere zeichnet sich die Erfindung durch eine Verwendung der zuvor beschriebenen Vorrichtung zum Verschweißen von elektrisch leitenden Elementen zur Herstellung einer knotenför migen Verbindungsstelle und anschließenden Umhüllen mit elek trisch isolierendem Material aus, wobei die elektrisch leitenden Elemente in einen ersten im Querschnitt einstellbaren Verdich tungsraum und anschließend die knotenförmige Verbindungsstelle in einen zweiten im Querschnitt einstellbaren Verdichtungsraum eingebracht werden, wobei die zum Verschweißen wirksamen Sonotrodenflächen der zwei Verdichtungsräume zum einen parallel und zum anderen senkrecht zur Sonotrodenschwingungsachse verlaufen.In particular, the invention is characterized by its use the previously described device for welding electrically conductive elements for the production of a knot connection and subsequent wrapping with elec trically insulating material, the electrically conductive Elements in a first compression adjustable in cross section room and then the knot-shaped connection point into a second compression chamber, adjustable in cross section be introduced, the effective for welding Sonotrode surfaces of the two compression rooms, on the one hand, parallel and secondly perpendicular to the sonotrode vibration axis run.
Weitere Einzelheiten, Vorteile und Merkmale der Erfindung erge ben sich nicht nur aus den Ansprüchen, den diesen zu entneh menden Merkmalen - für sich und/oder in Kombination -, sondern auch aus der nachfolgenden Beschreibung eines der Zeichnung zu entnehmenden bevorzugten Ausführungsbeispiels. Es zeigtFurther details, advantages and features of the invention ben not only from the claims to be found characteristics - for themselves and / or in combination - but also one of the drawings from the following description derived preferred embodiment. It shows
Fig. 1 eine Seitenansicht einer Sonotrode einer erfindungsgemäßen Vorrichtung und Fig. 1 is a side view of a sonotrode of a device according to the invention and
Fig. 2 eine Draufsicht der Sonotrode nach Fig. 1. FIG. 2 shows a top view of the sonotrode according to FIG. 1.
In den Figuren ist eine Sonotrode (10) einer vom Aufbau hinläng lich bekannten Ultraschallschweißvorrichtung dargestellt, die einen stabförmigen Sonotrodenkörper (12) mit im Endbereich vorhandenem Sonotrodenkopf (14) umfaßt. Die Sonotrode wird in Richtung ihrer Längsachse (18) in Schwingung gesetzt, um so die erforderliche Energie auf zu verschweißende Teile zu übertragen.In the figures, a sonotrode ( 10 ) of an ultrasound welding device known from the construction is shown, which comprises a rod-shaped sonotrode body ( 12 ) with a sonotrode head ( 14 ) present in the end region. The sonotrode is set in motion in the direction of its longitudinal axis ( 18 ) in order to transmit the required energy to the parts to be welded.
Erfindungsgemäß ist die Sonotrode (10) so ausgebildet und dieser Gegenelektroden oder Ambosse (18) und (20) so zugeordnet, daß wahlweise Metallteile oder Kunststoffteile mittels Ultraschall ver schweißt werden können. Da die Schwingungsenergie beim Metall schweißen parallel zur Schwingungsrichtung (18), beim Kunst stoffschweißen senkrecht zur Schwingungsrichtung (18) appliziert werden muß, werden senkrecht zueinander verlaufende Abschnitte (22) bzw. (24) des Sonotrodenkopfes (14) als Begrenzung von Verdichtungsräumen (28) und (28) gewählt, die im Querschnitt in bekannter Weise zum Einstellen auf die zu verschweißenden Teile einstellbar sind. Der Abschnitt (22) und damit die Längsachse des Verdichtungsraumes (26) verläuft parallel zur Schwingungsrich tung (16), so daß infolgedessen in diesem elektrische Leiter wie Kabel (30), (32) zur Erzielung eines Knotenpunktes (34) ver schweißt werden können. Der Verdichtungsraum wird folglich von dem Abschnitt (22) des Sonotrodenkopfes (14) und dem Amboß bzw. der Gegenelektrode (18) seitlich begrenzt, wobei die Stirn flächen des Verdichtungsraumes (26) offen sind. According to the invention, the sonotrode ( 10 ) is designed and this counterelectrodes or anvils ( 18 ) and ( 20 ) assigned so that either metal parts or plastic parts can be welded ver using ultrasound. Since the vibration energy for metal welding must be applied parallel to the direction of vibration ( 18 ), for plastic welding perpendicular to the direction of vibration ( 18 ), sections ( 22 ) and ( 24 ) of the sonotrode head ( 14 ) which run perpendicular to each other are used to delimit compression spaces ( 28 ) and ( 28 ) are selected, which are adjustable in cross-section in a known manner for adjustment to the parts to be welded. The section ( 22 ) and thus the longitudinal axis of the compression chamber ( 26 ) runs parallel to the direction of vibration ( 16 ), so that consequently electrical conductors such as cables ( 30 ), ( 32 ) can be welded to achieve a node ( 34 ) . The compression space is consequently laterally limited by the section ( 22 ) of the sonotrode head ( 14 ) and the anvil or the counter electrode ( 18 ), the end faces of the compression space ( 26 ) being open.
Die Verstellbarkeit des Verdichtungsraumes (26) kann dabei durch Aufspaltung des Ambosses (18) in zumindest zwei in unterschied liche Richtungen verschiebbare Teile erreicht werden.The adjustability of the compression chamber ( 26 ) can be achieved by splitting the anvil ( 18 ) into at least two parts that can be moved in different directions.
Nachdem die elektrischen Leiter (30), (32) verschweißt sind, wird der so gewonnene Knotenpunkt (34) in den Verdichtungsraum (28) eingelegt, um z.B. von streifenförmigen Kunststoffmaterialien (36) und (38) umhüllt zu werden. Um die hierfür erforderliche Energie zu applizieren, geht von der Stirnfläche (40) des Sono trodenkopfes (14) außermittig ein nasenförmiger Vorsprung (42) aus, der zusammen mit der Stirnfläche (40) selbst eine seitliche Begrenzung des Verdichtungsraumes (28) bildet. Die anderen Begrenzungsflächen werden durch den Amboß (20), und zwar durch einen sich in Richtung der Stirnfläche (40) sich er streckenden Vorsprung (44) sowie durch eine parallel zur Stirn fläche (40) verlaufende Fläche (46) gebildet. Durch diesen Aufbau ist die Schwingungsrichtung (16) der Sonotrode (10) senkrecht zu den zu verschweißenden Flächen der Kunststoffbänder (36) und (38) ausgerichtet, so daß das Kunststoffultraschallschweißen möglich wird.After the electrical conductors ( 30 ), ( 32 ) have been welded, the node ( 34 ) obtained in this way is inserted into the compression space ( 28 ) in order, for example, to be encased by strip-shaped plastic materials ( 36 ) and ( 38 ). In order to apply the energy required for this, a nose-shaped projection ( 42 ) extends from the end face ( 40 ) of the sonotrode head ( 14 ), which together with the end face ( 40 ) itself forms a lateral boundary of the compression space ( 28 ). The other limiting surfaces are located to he formed by the anvil (20), by a in the direction of the end face (40) stretching projection (44) and by a surface parallel to the end (40) extending surface (46). With this structure, the direction of vibration ( 16 ) of the sonotrode ( 10 ) is oriented perpendicular to the surfaces of the plastic strips ( 36 ) and ( 38 ) to be welded, so that plastic ultrasonic welding is possible.
Die Einstellbarkeit der den Sonotrodenabschnitten (22) und (24) zugeordneten Ambosse (18) und (20) wird durch die in den Fig. 1 und 2 eingezeichneten Pfeile verdeutlicht, wodurch ersichtlich wird, daß die Verdichtungsräume (26) und (28) an die Querschnitte der zu verschweißenden Teile anpaßbar ist.The adjustability of the anvils ( 18 ) and ( 20 ) assigned to the sonotrode sections ( 22 ) and ( 24 ) is illustrated by the arrows drawn in FIGS. 1 and 2, whereby it can be seen that the compression spaces ( 26 ) and ( 28 ) are on the cross sections of the parts to be welded can be adjusted.
Selbstverständlich kann die Sonotrode (10) bzw. der Sonotroden kopf (14) auch eine andere Geometrie aufweisen. Ausschlaggebend ist jedoch, daß diese Abschnitte zur Verfügung stellt, um Ver dichtungsräume auszubilden, in denen die zu verschweißenden Flächen der Metallteile parallel und die zu verschweißenden Flächen der Kunststoffteile senkrecht zur Schwingungsachse der Sonotroden ausrichtbar sind.Of course, the sonotrode ( 10 ) or the sonotrode head ( 14 ) can also have a different geometry. It is crucial, however, that these sections are available in order to form sealing spaces in which the surfaces of the metal parts to be welded are parallel and the surfaces of the plastic parts to be welded are aligned perpendicular to the axis of vibration of the sonotrodes.
